Anyhow, the -800s are needed to fly to airports that have shorter runway lengths that the -900s cannot feasibly take-off from/land on (such as SNA and SBA). They also need the -800 on many of their PDX routes as well, which requires less demand and fewer seats than their SEA routes do, even throughout the pandemic. I've also noticed that the -800s are often operating on Hawaii routes and the -700 variants are typically reserved for inter-Alaska flights. However, with the E175 operating within Alaska now, their long-term -700 variant fleet utilization strategy may end up changing overtime.
Alaska also needs as much capacity in Seattle as possible in order to compete against Delta.
These factors alone, leave most of the -900s in Seattle, but I'm sure there are other factors that play into this decision as well.

I thought SEA went by slots (not restricted slots, but flight frequencies) instead of actual seats, I could be wrong though. AS did block middle seats for awhile, but only recently started opening them up again IIRC.
